Polish for GDC

[davidyu]

• clicking on the swf should focus on the swf (we don't want to force the player to click in the swf because that shoots a missile). There should be an UI indicator and a missile should not be fired. DO NOT DO
• do not let player spam pings and blips.
• narrow down the range for ping reveals.
• the grid should fade out near the edge of the stage (like logo)
• place the player at an open respawn location
• revise map for 4p action
• UI to indicate # of players online and connected to current instance

GDC done. No new feature to salvage from this.
